Winter Olympics officials say the number two world ranking of the Australian women's aerial ski team is under threat, because the Queensland Government stopped the construction of a dedicated training facility.

The previous state and federal Labor governments promised $6.1 million to build a world-class aerial water jump pool at the Sleeman Sports Complex in Brisbane's east.

The athletes were preparing to move to Brisbane last year, when the Newman Government halted the project just before the 36-metre high jump ramps were installed.

The Olympic Winter Institute of Australia's chef de mission, Ian Chesterman, says the decision forced gold medallist Lydia Lassila to move to Switzerland to prepare for the games.

"It's been particularly hard for Lydia Lassila, who is a mother now, and who was looking forward very much to train at home and train to compete at home," he said.
